布局文件代码：

[html] view plain copy print ?

<ProgressBar
android:id="@+id/progressbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateDrawable="@drawable/progressbar"
/>

<ProgressBar 
				android:id="@+id/progressbar"
				android:layout_width="wrap_content"
				android:layout_height="wrap_content"
				android:indeterminateDrawable="@drawable/progressbar"
			/>

此XML文件新建在drawable目录下：文件名为：progressbar

[html] view plain copy print ?

<?xmlversion="1.0"encoding="utf-8"?>
<animated-rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:pivotX="50%"android:pivotY="50%"
android:fromDegrees="0"
android:toDegrees="360">
<shape
android:shape="ring"
android:innerRadiusRatio="3"
android:thicknessRatio="8"
android:useLevel="false">
<gradient
android:type="sweep"
android:useLevel="false"
android:startColor="#6BD3FF"
android:centerColor="#FF7121"
android:centerY="0.50"
android:endColor="#FFFF00"/>
</shape>
</animated-rotate>

<?xml version="1.0" encoding="utf-8"?>
<animated-rotate
 xmlns:android="http://schemas.android.com/apk/res/android"
android:pivotX="50%" android:pivotY="50%" 
android:fromDegrees="0" 
android:toDegrees="360">
 
 <shape 
 android:shape="ring" 
 android:innerRadiusRatio="3" 
android:thicknessRatio="8" 
android:useLevel="false"> 
<gradient 
android:type="sweep" 
android:useLevel="false" 
android:startColor="#6BD3FF" 
android:centerColor="#FF7121" 
android:centerY="0.50" 
android:endColor="#FFFF00" /> 
</shape> 
 
</animated-rotate>

至于设置水平进度条的颜色:

[html] view plain copy print ?

<LinearLayoutandroid:gravity="center"
android:orientation="horizontal"
android:padding="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<SeekBarandroid:layout_gravity="center"android:id="@android:id/progress"
android:paddingLeft="8.0dip"android:paddingRight="8.0dip"
android:paddingBottom="4.0dip"android:layout_width="fill_parent"
android:layout_height="wrap_content"android:maxHeight="2.0px"
android:progressDrawable="@drawable/progressbar_drawable"android:minHeight="2.0px"
android:thumb="@drawable/seekbar_thumb"style="?android:attr/progressBarStyleHorizontal"/>
</LinearLayout>

	<LinearLayout android:gravity="center"
		android:orientation="horizontal"
		android:padding="10dp" 
		android:layout_width="fill_parent"
		android:layout_height="wrap_content">
		<SeekBar android:layout_gravity="center" android:id="@android:id/progress"
			android:paddingLeft="8.0dip" android:paddingRight="8.0dip"
			android:paddingBottom="4.0dip" android:layout_width="fill_parent"
			android:layout_height="wrap_content" android:maxHeight="2.0px"
			android:progressDrawable="@drawable/progressbar_drawable" android:minHeight="2.0px"
			android:thumb="@drawable/seekbar_thumb" style="?android:attr/progressBarStyleHorizontal" />
	</LinearLayout>

progressbar_drawable.xml如下：

[html] view plain copy print ?
